EHEIM CO²Set400 without bottleTypically, aquarium water lacks sufficient carbon dioxide (CO2) since it has already been removed from the tap water during treatment. Alongside light, nitrogen, phosphates, and trace elements, CO2 stands out as a vital nutrient for aquatic plants. The healthier and more robust the plants, the lesser the likelihood of algae growth. Additionally, plants generate more oxygen, essential for fish respiration, and CO2 helps maintain balanced pH levels in the water when administered correctly.This set comes complete with essential accessories, including:Precision pressure regulator featuring manometers and an accurate dosing valve for use in reusable systems360° swiveling hose connectorCO²-specific safety hose, pressure-resistant, 3m, Ø 4/6 mmCO² safety diffuser equipped with a bubble counter and non-return valve for efficient CO² dosing5 water test strips to evaluate initial water parametersCO² long-term test and indicator reagent for continuous monitoring of CO² levels in the aquariumEasy and tool-free installationOptional accessories (sold separately): CO² magnetic valve (for nighttime shut-off)Produced in Germany3-year guarantee

The Aqua Medic Overflow box is designed to be mounted on the side or back wall of your aquarium. Once the overflow is activated, it maintains a consistent water level. Water circulation is facilitated by pumping water from the sump into the aquarium and then returning it through the Overflow box back to the sump. This setup allows aquariums to be connected to cabinet filter systems without the need for drilling holes in the tank. The Overflow box is constructed from durable acrylic and is available in two different capacities: OFB 2500, which supports up to 2,500 l/h (approximately 625 gph), and OFB 5000, which can handle up to 5,000 l/h (about 1,250 gph). Connection size: 32 mm. OFB 2500 (l x w x h): approximately 19x18x25 cm (about 8” x 7.2” x 10”) OFB 5000 (l x w x h): approximately 19x25x25 cm (about 8” x 10” x 10”)

Facilitates the monitoring of ammonium/ammonia levels in both fresh and saltwater Ammonium and ammonia primarily originate from fish excrement. They interchange based on the pH level. While ammonium is generally safe, ammonia poses a threat to fish health. The sera NH4/NH3-Test enables you to track the overall concentration of both substances (the current ammonia level can be determined using the pH value with the provided chart). If there is an immediate risk, sera toxivec (for freshwater) or sera pond toxivec (for ponds) can offer assistance. Additionally, sera bio nitrivec (freshwater), sera marin bio reefclear (marine water), or sera pond bio nitrivec (pond) effectively combat the persistent buildup of these compounds. Suitable for approximately 60 measurements.

EHEIM CO2 - 230V Magnetic ValveCO2 Magnetic Valves (Night Shut-Off) (Solenoid Valve)This magnetic valve allows you to easily turn off the CO2 supply in your aquarium when needed – for instance, to manage pH levels or during the night.By shutting off the CO2 supply overnight, you can save up to 50% of CO2, as photosynthesis occurs only during the day when plants take in carbon dioxide and emit oxygen. At night or in the absence of light, plants utilize oxygen, making CO2 fertilization unnecessary.The magnetic valve operates on 230V alternating current and performs optimally when linked to the aquarium light timer. This setup enables the magnetic valve to be turned off in sync with the aquarium lights.
